This review article provides information on the main directions in assessing the economic and biological characteristics of sweet cherry cultivars and forms at the present stage. The problem of the need for the study of sweet cherry cultivars for winter hardiness, frost resistance, drought tolerance, resistance to fungal diseases (especially coccomycosis and moniliosis) is considered in detail. The rationale for the need for a continuous search for cherry genotypes, distinguished by self-fertility and high biochemical properties, is given. The article argues that it is necessary to continue research in the field of productivity of sweet cherry cultivars, since the order of fruit formation, fruiting features, and placement of sweet cherry productivity elements are not fully understood and often contradict each other. Information on achievements in breeding, cultivar research and economic and biological assessment of sweet cherry in domestic and foreign research institutions is provided.
